IRS Disclosure Obligations for Trustees

I recently received a frantic call from Vincent. He’d meticulously drafted a trust for his mother, ensuring all her assets were protected and passed on smoothly to his sister and brother. Except, a critical codicil—the one specifically directing the distribution of a substantial stock portfolio—was misplaced during a move. After months of searching, it was declared lost. Now, his siblings are challenging the initial trust instructions, demanding a larger share of the portfolio, and Vincent is facing legal fees that are rapidly escalating. This underscores a painful truth: even the most beautifully drafted trust is useless if it isn’t properly funded and the necessary documentation is secure.

What Happens When a Trust Isn’t Fully Funded?

As an Estate Planning Attorney and CPA with over 35 years of experience here in Escondido, California, I see this far too often. People focus on creating the trust document, believing that’s the hard part. But signing the trust document is only step one—you must legally transfer assets (funding) to the trustee for the trust to exist. This is especially critical when dealing with complex assets like brokerage accounts, real estate, or business interests. Under California Probate Code § 15200, a trust is not valid unless it holds identifiable property.

What Assets Should Be Included in a Trust?

Ideally, everything you want to pass on through the trust should be titled in the name of the trust. This includes:

• Real Estate: Deeds must be formally re-titled to reflect the trust as the owner.
• Bank & Brokerage Accounts: Account registration must be changed to “The [Trust Name], dated [Date], with [Trustee Name] as Trustee.”
• Vehicles: Titles should be updated with the trust as the registered owner.
• Life Insurance & Retirement Accounts: Beneficiary designations should name the trust as the beneficiary (reviewing and updating these regularly is vital).
• Business Interests: Ownership structures (like LLC memberships) need to be properly assigned to the trust. As of March 2025, domestic U.S. LLCs held in a living trust are exempt from mandatory BOI reporting; however, trustees managing foreign-registered entities must still file updates with FinCEN within 30 days.

What if Assets Are Missed? The Safety Net Provisions

We all make mistakes. Sometimes, despite our best intentions, an asset slips through the cracks. For deaths on or after April 1, 2025, if a primary residence intended for the trust was accidentally left out (valued up to $750,000), it qualifies for a ‘Petition for Succession’ under AB 2016 (Probate Code § 13151). It’s important to understand that this is a Petition (requiring a Judge’s order), NOT an Affidavit. This is a valuable tool but requires prompt action and legal guidance. The Small Estate Affidavit is largely being replaced by this process for more complex scenarios.

How Does a CPA Benefit Trust Administration?

My dual role as both an attorney and a CPA gives me a unique perspective. The tax implications of trust administration are often overlooked. A key consideration is the “step-up in basis.” When assets are transferred into a trust, they don’t trigger immediate capital gains. But, when those assets are eventually distributed to beneficiaries, understanding the basis is critical. As a CPA, I can accurately determine this basis, minimizing potential capital gains taxes for your heirs. Proper valuation of assets is also vital, particularly for closely-held businesses or unique property.

What About Digital Assets and Access?

In today’s digital world, we can’t ignore digital assets – photos, emails, cryptocurrency, online accounts. Without specific RUFADAA language (Probate Code § 870) in your trust, service providers like Apple, Google, and Coinbase can legally deny your successor trustee access to these critical assets. It’s essential to include a clear digital asset provision granting your trustee the authority to manage and access these accounts.

What Does the Future Hold for Estate Taxes?

The federal estate tax landscape is constantly evolving. Effective Jan 1, 2026, the OBBBA permanently set the Federal Estate Tax Exemption to $15 million per person, meaning the primary focus of most Living Trusts is now avoiding probate and protecting privacy, rather than minimizing federal taxes. However, this doesn’t negate the need for careful planning, particularly for larger estates or those with complex asset structures. Furthermore, while transferring your home into your revocable trust does not trigger reassessment, the eventual distribution to your children will trigger a Prop 19 reassessment to current market value unless the child moves in as their primary residence within one year.

Can a Trust Be Changed or Revoked?

Most California trusts are revocable, meaning you retain the ability to modify or terminate them during your lifetime. Unless the trust instrument expressly states otherwise, Probate Code § 15400 presumes that all California trusts are revocable by the settlor, allowing you to amend, revoke, or restate the trust at any time while you have capacity.

What separates a successful California trust distribution from a costly battle over interpretation and accounting?

The advantage of a California trust is control and continuity, but this relies entirely on accurate funding and disciplined administration. Without clear asset titles and strict adherence to fiduciary standards, a private trust can quickly become a subject of public litigation over mismanagement, capacity, or undue influence.

To prevent family friction during administration, trustees must adhere to the rules in administering a California trust, while beneficiaries should monitor actions to prevent the issues highlighted in common trust pitfalls, ensuring the trusts is enforced correctly.

Ultimately, the success of a trust depends on the details—proper funding, clear terms, and a trustee willing to follow the rules. By anticipating friction points and documenting every step of the administration, fiduciaries can protect the estate and themselves from liability.

Verified Authority on California Trust Law

• Trust Validity (Probate Code § 15200): California Probate Code § 15200
  The foundational statute confirming that a trust requires property to be valid. This is the legal basis for the “funding” requirement—without transferring assets (deeds, accounts) into the trust, the document is legally empty.
• Revocability Presumption (Probate Code § 15400): California Probate Code § 15400
  Confirms that California trusts are presumed revocable unless stated otherwise. This grants the settlor the flexibility to change beneficiaries, trustees, or terms as life circumstances evolve.
• Primary Residence Succession (AB 2016): California Probate Code § 13151 (Petition for Succession)
  Effective April 1, 2025, this statute acts as a backup for funding errors. If a home (up to $750,000) is left out of the trust, this Petition avoids a full probate administration.
• Property Tax Reassessment (Prop 19): California State Board of Equalization (Prop 19)
  Essential for all trust creators. While the trust avoids probate, it does not automatically avoid property tax increases for heirs. Specific planning is required to navigate the “primary residence” requirement for children.
• Estate Tax Exemption (OBBBA): IRS Estate Tax Guidelines
  Reflects the OBBBA permanent increase to a $15 million per person exemption (effective Jan 1, 2026). This shifts the planning focus for most Californians from tax avoidance to asset protection and probate avoidance.
• Digital Asset Access (RUFADAA): California Probate Code § 870 (RUFADAA)
  Without this statutory authority included in your trust, your digital legacy (crypto, social media, cloud storage) may be permanently locked away from your family by service providers.
